Application filed April 8, 1915. Serial No. 19,964.

To alt whom it may concern Be it known that I. Hnaenn'r A. WEBSTER, a citizen of the United States,residing at Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Roughing Attachments for Horseshoes; and I do declare the following to be a full, clear, and exact description of the invention, such'as will enable other skilled in the art to which it appertains to make and use the same.

This invention relates to roughing attachments for horse shoes. 7 r

The object of the invention'is to provide a simply constructed and emcient attachment of this character which will be capable of withstanding the rough usage to which such attachments are subjected and which may be readily applied to and removed from ordinary horse shoes while on the horses feet without the aid of skilled labor or special tools. 1

Another object is to provide an attachment of this character with removable .or detachable toe calks which when worn or damaged may be removed from the attachment and readily replaced by new ones.

With these and other objects in view the invention consists of certain novel features of construction and the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings: Figure 1 represents a top plan view showing this improved attachment applied to a horse shoe; Fig. 2 is a side elevation thereof; Fig. 3 is a longitudinal vertical section taken on theline 33 of Fig. 1; Fig. 1 is a bottom plan view thereof; Fig. 5. is an enlarged detail per spective view of one of the links; and, Fig. 6 is a detail perspective view of the clamping member.

In the embodiment illustrated a horse shoe S of any suitable or ordinary construction is shown adapted to be attached to the horses hoof in the usual manner.

The improved attachment constituting this invention which may be applied to the horse shoe shown or any other comprises a front holding or clamping member 1 which is obtuse angled in form as shown in Figs. 1, 4c, and 6 and the diverging arms 2 and 3 of which are provided at their free ends with upturned retaining lugs at which are provided at their inner edges at points spaced from said arms with shoe engagingshoulders 5 which are designed to engage the inner face of the shoe S adjacent the front edge thereof as shown. A threaded bore 6 extends edgewise through the vertex of this obtuse angled member, said member being preferably enlarged laterally at this point to form a boss, the walls of which are of the necessary thickness to support a clamping bolt 7 which is designed for threaded engagement with the bore 6. This bolt 7 is provided with the usual angular head 8 and carries at its opposite end a shoe gripping element 9 which is here shown in the form of a plate having a laterally extending flange 10 at one edge thereof which is designed to fit over and engage the upper or inner face of the shoe S at the toe portion thereof. This shoe gripping plate 9 has a swiveled connection with the bolt 7 and is shown with a washer 11 arranged between the inner face thereof and the threads on the front end of the bolt so that when said bolt is tightened in the bore 6 the plate 9 is forced against the inner edge of the toe portion of the shoe, while the lugs 4: at the ends of the member 1 are removably engaged with the outer edges of the shoe at points spaced from said plate engaging portion at opposite sides of the shoe.

Arcuate links 12 are shown pivotally connected at their inner ends to the arms 2 and 3 of the member 1, said ends being rabbeted as shown at 13 and the reduced portions thereof are engaged with the inner faces of the arms 2 and 3, the rabbeted portion being of a depth corresponding to the thickness of said arms 2 and 3 so that when connected. the lower faces of these links are arranged flush with the lower faces of the arms 2 and 3. The free ends of these links 12 are provided with laterally extending arms 14: and 15 which project from opposite side edges thereof and are provided at their terminals with upturned shoe engaging lugs 16 which are designed to engage the inner and outer edges of the rear portion of the shoe at obliquely disposed points. The inner faces of these lugs 16 are inclined as shown at 17 to provide for their reliable engagement with the edges of the shoe and to adapt them to conform to the shape of the shoe at the rear ends thereof. The faces of the lugs 16 at the outer side of the link are inclined forwardly while those at the inner sides thereof are correspondingly inclined so that when the attachment is applied, these inclined faces reliably grip the opposite side edges of the rear portions of the shoe and thus securely hold said links in operative engagement with the shoe and yet adapt them to engage different portions of the rear part of the shoe such as'may be necessary when the device is applied to wider or narrower shoes.

From the above description it will be obvious that this improved roughing attachment may be quickly applied to horse shoes already on the feet of the horse by simply loosening the bolt 7 and placing the attachment in operative position on the shoe S with the plate 9 engaging the inner edge of the toe portion of the shoe and the lugs 4 engaging the outer front edges thereof, the lugs 16 of the arms 14 and 15 being engaged "with the rear portions of the opposite sides of theshoe.- When so positioned the bolt 7 is tightened thereby forcing the plate 9 forwardly against the inner edge of the toe portion of the shoe and drawing the memthe arms of said links.

her 1 rearwardly, causing the shouldered edges of the lugs 12 thereof to clampingly engage the front edges of the shoe. This backward movement of the member 1 caused by the tightening up the bolt 7 spreads the front ends of the arcuate links 12 and thus causes their lug carrying free ends to be forced into gripping engagement with the rear portions of the shoe and the attachment is thus securely clamped in operative position on the shoe ready for use.

'Calks 18 are detachably connected with the arms 2 and 3 of the member 1 preferably at points between the outer or free ends of said arms and the pivotal connections of the links 12 therewith. It is well understood that these calks when they become dull or broken may be readilyremoved and replaced by others. Similar calks 19 are mounted on the links 12 preferably adjacent These attachments may be made in various sizes to fit different sized shoes and are preferably made in three sires, small, medium andlarge H; Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

I claim as my invention:

1. A. roughing attachment for horse shoes comprising an obtuse angled front member having retaining lugs at its opposite ends, said lugs being provided on their inner edges with shoe engaging shoulders, a bolt extending edgewise through the vertex of said front member and adjustable there in, said bolt having a shoe gripping element at its front end swiveled thereto, calks carried by said member, arcuate links pivotally connected at one end with said front member, said links having arms at their front end extending laterally from opposite sides thereof and provided at their terminals with shoe engaging lugs, said lugs having their inner faces transversely inclined to facilitate their gripping engagement with the edges of a shoe, and calks carried by said links.

2. A roughing attachment for horse shoes comprising an obtuse angled front member having retaining lugs at its opposite ends, said lugs being provided on their inner edges with shoe engaging shoulders, a bolt extending edgewise through the vertex of said front member and adjustable therein, said bolt having a shoe gripping element at its front end swiveled thereto, calks carried by said member, arcuate links having their front ends recessed and pivotally connected with said front member on opposite sides of said bolt, said links having arms at their free ends extending laterally from opposite sides thereof and provided at their'terminals with upwardly extending shoe engaging lugs having their inner faces inclined transversely to facilitate their engagement with the edges of the shoe.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
